Time-shift attack in practical quantum cryptosystems
Bing Qi, Chi-Hang Fred Fung, Hoi-Kwong Lo +1
Recently, a new type of attack, which exploits the efficiency mismatch of two single photon detectors (SPD) in a quantum key distribution (QKD) system, has been proposed. In this p…
Security of Quantum Key Distribution with Realistic Devices
Xiongfeng Ma
We simulate quantum key distribution (QKD) experimental setups and give out some improvement for QKD procedures. A new data post-processing protocol is introduced, mainly including…
Experimental Quantum Key Distribution with Decoy States
Yi Zhao, Bing Qi, Xiongfeng Ma +2
To increase dramatically the distance and the secure key generation rate of quantum key distribution (QKD), the idea of quantum decoys--signals of different intensities--has recent…
Practical Decoy State for Quantum Key Distribution
X. Ma, B. Qi, Y. Zhao +1
Decoy states have recently been proposed as a useful method for substantially improving the performance of quantum key distribution. Here, we present a general theory of the decoy…
